　　July 17, the first day of the school trip

　　. During the summer vacation of the second year of high school, the original destination was changed to a small island called Ormi Island, which floats in the center of the Pacific Ocean. The long journey did not reduce the interest of the students of Laizen High School. From the sky, Ormi Island is a moon-shaped peninsula. Because of its unique shape, it attracts countless tourists, although it was cut into this shape due to space earthquakes.

　　The flight from Amamiya City to the destination took a total of three hours. Shidou sat in the middle of the three rows of seats, with Origami and Tohka sitting perfectly on his left and right...

　　"Shidou, look, you can see the sea outside the window, come closer."

　　"Shidou, we just passed through the clouds, they looked like cotton candy."

　　"Shidou, does that cloud look like Tohka Yatogami getting angry?"

　　"...That's Tohka herself reflected in the glass."

　　Origami, who took the window seat first, kept pulling at the cuffs of Shidou's short sleeves, drawing his attention in her direction.

　　"Guuuuuu... Origami Tobiichi, you guy! Shi, Shidou, I have breasts here too... Look, breasts!" Tohka, who was sitting in the aisle seat, pinched Shidou's chin and forced his head to turn towards the flight attendant on her side. Because it was so sudden, one could hear the "cracking" sound of his cervical vertebrae, but because it was Shidou, no one sympathized with him.

　　"It hurts... Tohka, please stop being awkward, my neck is going to break!" Shidou groaned in pain due to Tohka's strange strength, but before one wave of pain subsided, another wave arose. Origami on the other side grabbed Shidou's wrist and pulled it towards her... He was (forced) to maneuver between two beautiful girls in a strange posture, making the audience wonder whether they should envy him or sympathize with him.

　　"Yatogami Tohka... let Shidou go"

　　"Mmm... you should let go!"

　　"... Tohka... Origami..." Shidou's groaning continued, and the two of them glared at each other, with no sign of letting go.

　　"..."

　　"Hmph..."

　　"That's enough!" After finally finding a chance to catch his breath, Shidou immediately unfastened the safety buckles on the table and chair.

　　"I'm going to the bathroom!"

　　"Shidou, I'm going too!"

　　"Then I'll go too"

　　"Don't follow me..."

　　Origami and Tohka stood up, but Shidou had already run away. By the way, this kind of "battle for Shidou" has been staged four times since they got on the plane. If he doesn't run away, the first place Shidou will go after getting off the plane will probably be the hospital. However, since they are about to reach their destination, he will probably stay there until the landing this time.

　　"Shidou..." Tohka looked at the direction where Shidou left with a slightly lonely expression, and then her eyes fell on the row of seats in the corner... Her breathtakingly beautiful face instantly turned red, and she immediately sat back in her original seat. The toilet and the person sitting in the corner reminded her of the time when she was in the toilet of Shidou's house, having sex and defecating while having sex with that huge cock inserted into her vagina.

　　Origami also followed Tohka's line of sight and found the huge guy in the corner - a classmate named Daiki Dangan.

　　While sighing that this person's stealth performance had improved again, Origami walked to his side. Although he was so big, it seemed that no one noticed him except a few boys who talked to him and the class teacher, and he was the only one in his row.

　　This was definitely not a bullying incident. In addition to Daiki's popularity among girls being the last, he had a good relationship with the boys in the class. The reason why he occupied a row was just because his body took up too much space... making the people sitting next to him feel particularly stuffy.

　　"Daiki, move your feet, can I sit here?"

　　"...Are you asking after you've sat down?"

　　Origami occupied the window seat again, a seat where she could enjoy the view outside the plane window, but Daiki didn't grab it, and she didn't seem crowded sitting next to Daiki with her petite body.

　　"What are you doing?"

　　"Sleeping," Daji said with his eyes closed.

　　"Are you afraid of heights? Airsick?"

　　"...Pfft, stop talking nonsense. No, no, I'm not afraid of heights. I just played games all night and didn't wake up!" Daji explained in a panic, but when he turned his head and looked at Origami, he

　　immediately sat up straight and closed his eyes. Origami had noticed that Daji was not right. If it was normal for Daji to see her, his thieving eyes would always start from her feet and lick her whole body. If he made eye contact with Origami, he would immediately turn his head away, and then continue to stare at her again after a while. Origami had long been accustomed to men looking at her like this, but she was the first one who felt that he could eat people with his eyes like Daji.

　　But now, Daji's lustful energy was gone, and he

　　closed his eyes with a pale face. Excluding food poisoning and lack of sleep, there was only one possibility left - this guy was afraid of heights. Discovering Daji's unexpected weakness, Origami smiled faintly for a moment, but no one could see this rare smile.

　　"Is this your first time on a plane?"

　　"Yes, is there anything wrong?"

　　"It's my first time on a civilian plane too. It's different from a military transport plane and feels very fresh."

　　"Really? That's great (good reading)"

　　"Yeah, the seats are very comfortable and you can see out the window."

　　"If you don't have anything to do, can you go back to your seat? It's still uncomfortable here... it hurts." Daiki's unpleasant answer was met with a kick from Origami on his calf, which was kicked by Kotori not long ago. Although Origami controlled the strength, her combat training made her attack stronger than Kotori, which immediately woke Daiki up from his daze.

　　"I have something important to ask you for help." The silver-haired doll had no apology for having just hit someone, and was expressionless as always.

　　"It hurts so much! Every time you say something important, you end up investigating Shidou's use of tissues or collecting Shidou's used tableware. Didn't I just report to you about Shidou's breakfast this morning!"

　　Daiki rubbed the place where he was kicked, looking very painful.

　　"Since you received my payment, isn't it natural for you to do these things?"

　　"The payment you mentioned is just a few porn books! And they're all about flat-breasted girls! And the styles are mostly about silver-haired girls!" Although they were all torn up by Kurumi after she received them.

　　"Are you not satisfied?"

　　"Not...very satisfied."

　　Feeling the murderous aura slowly emanating from Origami, Daiki immediately corrected her wording.

　　"Then what do you want me to help with this time...it's not going to be collecting Shidou's changed clothes..."

　　"I can do that myself. I remember that you and Shidou were in the same room when we were assigned to the teams, right?"

　　"Uh...what are you going to do..."

　　"It's simple. Once you get the room key, leave it here for three minutes.

　　" "...As expected."

　　If she didn't do something for such a rare opportunity to stay in the same hotel with Shidou, she wouldn't be the pervert named Origami Tobiichi.

　　"Then it's settled." Origami unilaterally decided the matter, and then continued, "Now, you're not dizzy anymore, are you?"

　　"Could it be that you kicked me just now because..." Daiki realized that Origami's kick helped him distract from his fear of heights, and for this, he was full of gratitude to Origami, no wonder. While they were talking, the plane broadcast had already issued a landing warning.

　　——The first day of the school trip was a group activity, the route was to visit the island first, and then check into the hotel in the afternoon. The second and third days were individual activities.

　　"This... Is this the sea... Oh!"

　　After walking out of the airport, Tohka waved her arms at the beautiful scenery that could not be taken in without turning her head. On the other side of the road was the beach and the sea, and the horizontal line that divided the sky and the earth connected the blue sky and the ocean reflecting the sun.

　　"Tohka, let's go, I'm going to leave you behind."

　　"Oh! Come right away!"

　　When Tohka was still stunned by seeing the sea for the first time, everyone in the school had already set off for the gathering place, and only a few groups of three or two were still following Shidou and Tohka.

　　"Let me think... the first stop is the museum. We should take this road... turn left... and go straight..."

　　"Shidou Shidou, look, there's a huge banana floating on the sea! Can we eat it?" Tohka stopped and waved one hand to attract Shidou's attention, while pointing at the banana boat on the beach with the other hand. She was as innocent and cute as a little child.

　　"Haven't you seen that at the Ocean Park? You can't eat it."

　　"Shidou Shidou, oh oh! Is that a shark? I saw it in a movie that Yoshino watched. It was the kind that eats people!"

　　"That's also an inflatable toy..."

　　"Shidou Shidou..."

　　"Are you done yet... I can't see anyone ahead."

　　"Um... sorry." Shidou's voice gradually lost patience, as if he understood Shidou's impatience. Tohka had to shrink her head in grievance and follow behind him.

　　"…Hmm?"

　　"Tohka? What's wrong? If we don't move on, we'll really fall behind."

　　Before they had walked far, Tohka froze in her spot again. She heard a surprised voice from behind. Shidou turned around and saw Tohka looking up at the sky.

　　"Shidou, look..."

　　"What's wrong again...huh?"

　　Looking in the direction of Tohka's finger, the sky that was bright just now seemed to be covered with a thin layer of black gauze. The clouds seemed to be stirred by an invisible hand, forming a swirling vortex at an unreasonable speed. The surrounding scenery was also changing at an alarming speed, from clear to cloudy in just a moment.

　　The wind whistled past, and the ground seemed to be shaking because of it. The trash cans placed on the roadside also turned over, not to mention the rough waves on the coast. The strong typhoon spread across the entire island in an instant.

　　"Tohka, are you okay? There's a typhoon, let's hurry to the archives!"

　　"Shidou! Be careful!"

　　As he spoke, Tohka rushed over and pushed Shidou's body away, and then, a metal trash can hit Tohka's head heavily.

　　"Gah!" After a slightly funny cry, Tohka fell to the ground on the spot.

　　"Hey! Tohka! Wake up! Tohka!"

　　Shidou called out in panic and shook Tohka's shoulders, but she showed no signs of waking up... So he had to carry Tohka, who was unconscious in such a funny way, on his back and headed towards the archives... In front of him, where he had taken the wrong road, there were two identical orange-haired girls waiting for him, and they were having their final showdown...

　　——

　　"... Walk faster, Shidou and the others are gone"

　　"This is already my fastest speed, ahem, this typhoon is a headwind, and it was clearly said that it would be sunny when we went out

　　." After getting off the plane, because Daiki and Origami were sitting in the corner of the plane, as more and more students got off the plane, they were unable to meet up with Shidou, and in addition, a fat guy walked particularly slowly...

　　With Origami's guidance, Daiki was able to follow the original route to the archives, while Shidou and Tohka, who were a hundred meters ahead of them, took the wrong road after the typhoon arrived, and disappeared directly from Origami's sight.

　　"Focus on walking..." Origami followed Daiki's steps and walked behind him.

　　"Miss Origami...if you're in a hurry, you can go first by yourself..."

　　"No," Origami flatly rejected Daiki's proposal. "Without you blocking the wind, I'll be blown away. My body size will come in handy."

　　"...I can't be happy at all! Ahem." As soon as he opened his mouth to speak, Daiki was choked by the wind again.

　　The archives, which was the first gathering place, was not far away. It was specially built near the airport to cooperate with the development of the local area, but Daiki had a hard time walking.

　　"It's going to rain hard soon, walk faster."

　　For some reason, Origami, who was following behind Daiki, felt a sense of security from the bottom of her heart, even though this fat man was timid and unreliable...

　　"You're not wondering how something as big as yourself could get into my anus, are you?"

　　"Ehhh!! Origami, how do you know, can you read minds?"

　　"Ah..."

　　And he was thinking about evil things all the time... But looking at his back, Origami felt extremely relieved.

　　——When.they finally got to the archives, most of the students from Zen High School and tourists who came to take refuge had gathered inside.

　　"It's great that we made it before the rain." Origami walked out from behind Daiki and entered the archives first, looking for Shidou.

　　"No... It started raining halfway... It just hit me!!!" Daiki shouted angrily. Because it was a headwind and the wind was particularly strong, Origami, who was hiding behind him, didn't get wet at all. 

"Thank you for your hardwork," Origami said calmly as always, "Shidou... It seems he hasn't arrived yet... I hope nothing happened."

　　...

　　A strong storm swept across the island, coming quickly and leaving quickly. Just when the typhoon stopped and the sky cleared up, Shidou stepped into the archives... and ran into Origami who was about to run out to find him.

　　"...…"

　　"…Hi…Origami"

　　Origami frowned and her eyes became sharper than she could confirm the safety of the person she likes… The reason was that Shidou was carrying Tohka on his back, who seemed to be in a coma, but on his left and right were twin girls wearing the summer uniform of Raizen High School. The girl on the left had her bright orange hair tied up high behind her head, with a fearless and arrogant look on her face, while the girl on the right had her long hair braided into a braid, her mercury eyes half-closed, and she looked listless.

　　The two girls caressed Shidou's body intimately from left to right…

　　"Shidou~ What do you think? Compared to Yuzuru, I am more attractive, right? Now you can be forgiven for anything you do to me."

　　"Temptation. Kaguya's skills are not comparable to those of , so please choose Yuzuru."

　　"Shidou… Who are they… They are wearing our school uniforms, but I have never seen them before."

　　"Gokawa-san has just arrived and he's already hooked up with a new girl!?"

　　"And they are twins!!! Are you jealous of us to death!"

　　"Hey, a killer company? Yes, that Gokawa Shido."

　　Under the murderous gazes of all the students in the school, Shido walked into the archives on thin ice.

　　"They are transfer students..." A sleepy voice interrupted the students' noise, "...I asked Shi...Gokawa to pick them up. You guys come with me. Gokawa, take Tohka to find a place to rest."

　　Reine's timely appearance saved Shido.

　　——

　　"...So you originally came here for a tour, but you started arguing on the way here, so you started the last duel to decide the name of the Eight Dances early? The typhoon just now was also caused by your quarrel?" Reine had heard about the incident from Shido. On the way to the archives, these two girls who claimed to be elves fell from the sky and inexplicably became witnesses to their duel. With their own supplements, Reine already had a clear idea of the whole thing.

　　"That's right! This is the final duel between me and Yuzuru, and the one who wins in the end can replace the other and become the real hurricane spirit - Yamai. Well~ But of course I will be the winner in the end. Charming a man is no problem at all, right, Shidou? In fact, you already want to do all kinds of things to me, right? As long as you choose me, you can do whatever you want from now on."

　　"Refute. The gap between Kaguya and Yuzuru is obvious at a glance. You should choose Yuzuru who has bigger breasts here (laughs)"

　　"It's not that different! Do you want to fight!"

　　"Explanation. If Shidou hadn't barged in just now, Yuzuru would have won long ago."

　　Reine held her forehead. These two quarreling voices would have started quarreling in just a few words.

　　"...The last item is about charm?"

　　"That's right! As the 100th contest, let Shidou, who we met by chance, be the referee this time!"

　　Reine and the others' job is to seal spirits. The fact that these two are willing to become one person is a great help to her, but the problem now is that Shidou... replaces the other party, which means the other party will disappear, and Shidou must know this.

　　"What if Shidou doesn't choose between you two? You also saw that the girl he just carried on his back and the one with white hair..."

　　"Agreed. It's true that both of them are as cute as Yuzuru, so may I ask, what should we do?

　　" "I'm just making a suggestion. How about finding another candidate referee? If Shidou doesn't choose between you two, there will be a fourth person to make the judgment. Of course, this is your duel, you decide the candidate yourself."

　　"Huh, I always feel like I'm being looked down upon. Just a mere Shidou, as long as I release the shackles of darkness, the bipedal beast with a mortal body will immediately turn into a symbol of sharp teeth on the moonlit night." Kaguya raised his flat chest and posed an exaggerated pose and said.

　　"An, Anhe...what? What on earth is this kid talking about..."

　　"Kaguya Said that she is very powerful when she takes off her clothes, and men will immediately turn into big perverts when they see her.

　　" "..." Reine was completely silent about the special way the Yamai sisters said it. This unique tacit understanding between the two is the proof of their deep feelings. Reine didn't know it until not long after.

　　"So, there is no need for candidates at all. Snatching Shidou from others can prove Kaguya's charm."

　　"I agree. There is no reason for Yuzuru to lose.

　　" "Well...it's up to you, but Shidou is also very difficult to deal with. If you want to take him down, you still have to listen to me. There will be no harm."

　　The two cute little heads nodded in agreement, and the strategy for Shidou was launched under the secret discussion of the three.

　　In any case, the sealing of Yamai is the top priority at present. According to the previous intelligence, they are famous "berserkers", and the space shock level is also A-level that Touka can't reach. Although they appear in the sky above the Pacific Ocean every time, the fact that they will become a moving typhoon as long as they quarrel is enough to prove their harm.
